Lead to Believe

This is a little far-fetched to me. The New York Times has a whole article on the theory that violent crime decreased as a result of unleaded gasoline. Do I think that it has something to do with that? I really don't know. I'm glad it's gone, as there are certainly a lot of health hazards associated with lead, but that it was the cause of a crime wave? That doesn't sound right. On the other hand, the Roe effect (i.e. those who were more likely to be criminals started getting legally aborted in 1973) seems to be more the cause of that decrease. By pure coincidence lead began its phase-out in the same year that Roe v. Wade started phasing out unwanted children.
